Endometrial carcinoma (EC) is a common malignancy of the female reproductive system. Rab35 is widely recognized as an oncogenic driver and has been implicated in the progression of various malignant tumors. However, its regulatory mechanism and pathobiological roles in EC remain unclear. Rab35 expression in EC was systematically profiled via integrative analysis of clinical endometrial specimens and multi-omics databases (CPTAC and GEO). The association between clinical prognosis and Rab35 expression was examined using Kaplan-Meier analysis. Mechanistic investigations included transwell assays, western blotting, and immunofluorescence in Rab35-overexpressing and CRISPR/Cas9-mediated Rab35-knockout EC cells. A mouse xenograft tumor model was established to confirm the effects of Rab35 in vivo. The Rab35 content increased gradually from normal endometrium to atypical hyperplastic endometrium to EC. Moreover, the findings indicated that elevated Rab35 expression was significantly associated with advanced disease characteristics and poor overall survival in patients with EC. In addition, Rab35 enhanced the migratory and invasive nature of EC cells. The expression of Rab35 was inversely linked to that of the β-catenin destruction complex-related proteins Axin-1 and GSK3β, leading to the increased nuclear translocation of β-catenin in EC cells. Animal experiments further verified that Rab35 augmented EC progression by regulating the nuclear translocation of β-catenin. The study revealed that high expression of Rab35 was strongly correlated with EC progression and a poor clinical outcome. Furthermore, Rab35 promoted EC cell metastasis by accelerating the nuclear translocation of β-catenin. These findings suggest that Rab35 serves as a valuable biomarker and therapeutic target for EC.

Increasing evidence indicates that modulating pyroptosis in endothelial cells (ECs) can alleviate atherosclerosis (AS) progression; however, despite reports that nucleolin (NCL) regulates vascular smooth muscle cell proliferation in AS, the potential mechanism by which cell surface NCL mediates pyroptosis in ECs during AS remains poorly understood. AS was induced in ApoE AS model mice developed severe aortic lesions accompanied by pronounced EC pyroptosis and inflammation, together with elevated NCL expression in ECs of the aortic root. Both inhibition of NLRP3 and NCL knockdown alleviated atherosclerotic lesion severity in ApoE This study demonstrates that, in AS, NCL exacerbates EC pyroptosis and promotes disease progression by facilitating nuclear transport of RASSF2. This study defines the mechanistic roles of NCL in AS, thereby identifying a new molecular pathway and suggesting potential therapeutic targets. Show less

Clinical application of mesenchymal stem cells for endometrial repair has been hampered by variability in cell quality, large-scale production, and uncertainty regarding the optimal delivery route. In this study, we investigated the therapeutic potential of clinical-grade human embryonic stem cell-derived immunity-and-matrix-regulatory cells (IMRCs) for treating refractory moderate-to-severe intrauterine adhesion (IUA). In a rabbit IUA model, sub-endometrial injection of IMRCs significantly reduced fibrosis and enhanced endometrial angiogenesis, outperforming uterine perfusion. Transcriptomic analysis revealed distinct pro-angiogenic gene expression profiles between the two delivery routes. In vitro, IMRCs co-cultured with endometrial stromal cells (ESCs) markedly enhanced angiogenic potential compared to either cell type alone. Protein array analysis of the co-culture supernatant showed elevated levels of angiogenic factors, with functional assays confirming that inhibition of ANGPTL4, a non-canonical pro-angiogenic mediator, impaired angiogenesis. In a first-in-human, single-center, phase 1 dose-escalation trial involving 18 patients with refractory IUA, high-dose sub-endometrial IMRC injection promoted angiogenesis, reduced uterine scarring, and improved pregnancy outcomes, with no safety concerns observed over 3 years of follow-up. These findings highlight the translational promise of IMRCs as a novel therapeutic strategy for endometrial regeneration in severe IUA. Show less

Abdominal aortic aneurysm (AAA) is a life-threatening vascular disorder characterized by progressive aortic wall degeneration, inflammation, and vascular smooth muscle cells (VSMCs) loss. Despite extensive research, no effective pharmacological treatment is currently available to prevent or halt AAA progression. This study aimed to discover effective therapeutic agents for AAA and identify potential natural compounds with pharmacological efficacy against the disease by targeting matrix metalloproteinase-2 (MMP2), a key enzyme involved in extracellular matrix degradation and aneurysm progression. An integrated screening strategy combining cytotoxicity evaluation, high-content immunofluorescence imaging, and molecular docking was applied to an angiotensin II (Ang II)-stimulated rat aortic smooth muscle cells (RASMCs) model. A total of 138 natural products were systematically assessed. The anti-aneurysmal efficacy of the identified compound was further validated in both CaCl₂-induced and Ang II-infused ApoE Salvianolic acid B (Sal B), a major polyphenol from Salvia miltiorrhiza, was identified as a potent anti‑AAA candidate. It suppressed aneurysm formation, reduced elastin degradation, and attenuated inflammatory infiltration in vivo, while preserving the contractile phenotype, lowering ROS, and inhibiting MMP activity in Ang II‑stimulated RASMCs in vitro. Mechanistically, Ang II suppresses NRF2, leading to downregulation of the System Xc⁻-GPX4 axis and promoting lipid peroxidation and VSMC ferroptosis. This ferroptosis then activates the AGE-RAGE pathway, amplifying inflammation and MMP‑driven matrix degradation. Sal B counteracts this cascade by restoring NRF2 activity, improving lipid metabolism, and inhibiting MMPs, thereby blocking ferroptosis‑initiated inflammation and preserving aortic integrity. Salvianolic acid B exerts protective effects against AAA by attenuating oxidative stress, ferroptosis, and inflammation. These findings highlight Sal B as a promising natural therapeutic candidate for the prevention and treatment of abdominal aortic aneurysm. Show less

DUSP6, a dual-specificity phosphatase, has become a focal point in understanding the pathogenesis of various liver disorders. This study aims to investigate the role of DUSP6 in liver fibrosis and explore the underlying mechanism. Using a CCL4-induced mouse model, the consistent upregulation of DUSP6 expression was observed. Notably, when Dusp6 was knocked down, liver fibrosis showed significant improvement, revealing a protective effect intricately linked to the ERK pathway. This was accompanied by an increase in ferroptosis-related proteins SLC7A11 and GPX4, underscoring the role of ferroptosis, an iron-dependent form of regulated cell death, in this process. Transcriptomic analysis further revealed a crucial downregulation of Cyp2e1 following Dusp6 knockdown. In vitro, DUSP6 knockdown not only promoted ERK phosphorylation but also suppressed CYP2E1 expression, enhancing cell proliferation, bolstering hepatocyte resistance to ferroptosis, and alleviating hepatocyte injury. Importantly, inhibiting CYP2E1 in mouse models of liver fibrosis effectively slowed the progression. These findings illuminate a critical regulatory mechanism that DUSP6 regulates liver fibrosis via targeting ferroptosis, offering new a direction for therapeutic strategies in liver disease.

Acute alcohol consumption is known to exert widespread physiological effects, yet the immediate impacts on metabolic biomarkers remain incompletely understood. The present randomized controlled trial was conducted to investigate the acute effects of a single episode of alcohol ingestion on various biomarkers in healthy individuals. A total of 45 male participants were recruited and randomized into an alcohol group (n = 40) and a control group (n = 5) at an 8:1 ratio. Volunteers in the alcohol group ingested 40% Absolut vodka within 15 min. Blood pressure, heart rate, and blood oxygen saturation were measured at 0 h, 1 h, 3 h, 5 h, 12 h, and 24 h. Venous blood samples were drawn at 0 h, 1 h, 5 h, 12 h, and 24 h after alcohol intake. Our results showed that levels of liver function markers, including α-fucosidase (AFU), albumin (ALB), and alkaline phosphatase (ALP), were significantly increased in the alcohol group compared to the control group. The 24-h area under curve (AUC) of AFU, ALB, and ALP were significantly higher in the alcohol group. The liver fibrosis maker collagen type Ⅳ (Ⅳ-C) tended to be higher at 1 h and 12 h in the alcohol group compared to the control group. Lipid levels, including triglycerides (TG), apolipoprotein A1 (APOA1), and the APOA1/APOB, were significantly elevated after alcohol ingestion, particularly at 5 h and 12 h. The 24 h-AUC of TG, APOA1, and APOA1/APOB were higher in the alcohol group than in the control group. Additionally, cardiac function indicators, including heart rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP), were significantly elevated in the alcohol group. SBP and DBP remained higher 24 h after alcohol ingestion compared to the control group. This study demonstrated that even a single episode of binge drinking could induce significant alterations of biomarkers related to liver function, cardiac function, and lipid profiles. These findings provided valuable insights into the short-term impact of alcohol on health and highlighted the importance of further research to explore the long-term implications of repeated acute alcohol exposure. Given the very small control group, these results should be interpreted as preliminary and confirmed in larger, more balanced randomized trials.

Given the limitations of current treatments for Alzheimer's disease (AD), this study aims to comprehensively evaluate the therapeutic efficacy of human umbilical cord mesenchymal stem cells (hUCMSCs) in AD mouse models through a systematic review and meta-analysis. Additionally, we explore the impact of transplantation dose and route on treatment outcomes to identify the optimal window for clinical application. In accordance with the PRISMA guidelines, we systematically searched four major databases to identify randomized controlled trials involving hUCMSCs in AD mouse models. We used the standardized mean difference (SMD) to synthesize effect sizes and performed subgroup analyses based on pre-defined transplantation routes and doses. A total of 13 studies were included in the analysis. The meta-analysis revealed that hUCMSCs transplantation significantly improved spatial learning and memory in AD model mice, with a marked reduction in escape latency (SMD = -2.55; 95% CI: -3.34 to -1.75; Human umbilical cord mesenchymal stem cells can improve behavioral and pathological outcomes in AD mouse models via multiple mechanisms of action. The intravenous route using medium to high doses emerges as a critical factor for achieving optimal effects, providing important evidence and informing future experimental design and clinical translational research.

This study aimed to analyze the clinical features, genetic basis, and management of late-onset carbamoyl phosphate synthetase 1 deficiency (CPS1D) through a pediatric case report and literature review, highlighting diagnostic challenges and therapeutic strategies. We present a 19-year-old female with recurrent neurological symptoms since age 8. She underwent comprehensive metabolic screening, neuroimaging, and whole-exome sequencing of theCPS1gene. Identified variants were assessed for pathogenicity using multiple orthogonalin silicoprediction tools. The patient's initial hyperammonemic crisis at age 8 was misdiagnosed as encephalitis. Workup at age 13 confirmed hyperammonemia (peak 168 µmol/L), hypocitrullinemia, and elevated glutamine. Genetic analysis identified compound heterozygousCPS1variants: a novel c.1058 T > C (p.F353S) and known pathogenic c.1145C > T (p.P382L). A self-selected low-protein diet controlled acute crises but led to severe growth failure (height 145 cm, weight 30 kg). Late-onset CPS1D's nonspecific neurological symptoms often lead to misdiagnosis. Diagnosis requires a high index of suspicion, integrating metabolic profiling with genetic confirmation. This case expands the pathogenic genotypic spectrum of CPS1D. It crucially highlights that while dietary management is life-saving, it requires expert multidisciplinary oversight to prevent devastating consequences like growth failure, especially in resource-limited settings. Routine ammonia testing in unexplained encephalopathy is paramount. Show less

Recent evidence has shown that bone marrow mesenchymal stem cells (BMSCs) have multiple biological applications and play an important role in improving cognitive dysfunction. However, it is still unclear whether BMSCs play a role in cognitive impairment induced by chronic pain. This study aimed to evaluate the therapeutic effect of BMSCs on neuropathic pain-induced cognitive dysfunction and explore its potential mechanisms. A mouse chronic constriction injury (CCI) model was established, and the new object recognition task and fear conditioning were used to detect cognitive function; the expression of CXCL12/CXCR4 in blood and hippocampus was detected. After intravenous injection of BMSCs, changes in cognitive function and expression of the CXCL12/CXCR4 pathway, dentate gyrus neurogenesis, and excitability of hippocampal neurons were detected. In addition, induction of cognitive impairment in normal mice by CXCL12 recombinant protein was used to clarify whether the CXCL12/CXCR4 pathway mediates the cognitive function improvement effect of BMSCs. Our results found CCI mice showed significant cognitive impairment 21 days after surgery, with significantly increased expression of CXCL12/CXCR4 in blood and hippocampus. Intravenous injection of BMSCs significantly improved cognitive function, inhibited expression of CXCL12/CXCR4 in blood and hippocampus, promoted neurogenesis in dentate gyrus of CCI mice, and increased expression of BDNF and c-Fos in the hippocampus. In addition, BMSCs alleviate cognitive impairment induced by intravenous injection of CXCL12 recombinant protein in mice. In summary, BMSCs improve chronic neuropathic pain-induced cognitive dysfunction through peripheral blood CXCL12/CXCR4, and BMSCs may develop into therapeutic targets for chronic pain induced cognitive impairment.

Diabetic peripheral neuropathy (DPN), a severe complication of diabetes, is a key risk factor for diabetic foot (DF) that contributes highly to amputation and mortality. The pathogenesis of DPN remains unclear and complex, with no effective treatments currently available. Monoamine oxidase (MAO), a flavin adenine dinucleotide (FAD)-dependent enzyme, catalyzes the oxidative deamination of critical biogenic amines. The MAO family comprises two subtypes, MAOA and MAOB, which play distinct roles in pathophysiology. In this study, we identified that MAOB but not MAOA is pathologically upregulated in the sciatic nerve (SN) tissues of DPN patients and in the SN/dorsal root ganglion (DRG) tissues of DPN model mice. Notably, the selective MAOB inhibitor Khellin (Khe) effectively alleviated DPN-like pathology in mice. To explore the mechanistic role of MAOB in DPN, we performed proteomic profiling of DRG tissues from DPN mice and validated the findings using a MAOB-specific knockdown DPN mice model treated with adeno-associated virus (AAV) 8-MAOB-RNAi. Our results demonstrate that Khe targets MAOB to mitigate DPN pathology through HIF-1α/BACE1/Aβ/NLRP3/tau pathway, mediated by Schwann cell/DRG neuron crosstalk. All findings suggest that selective MAOB inhibition represents a promising therapeutic strategy for DPN, with Khe as a potential candidate for clinical translation against this disease. Show less

We examined whether the excess cardiovascular disease (CVD) risk among adults with steatotic liver disease (SLD) subtypes could be reduced or eliminated through joint control of low-density lipoprotein cholesterol (LDL-C), lipoprotein(a) [Lp(a)], and high-sensitivity C-reactive protein (hs-CRP). This prospective cohort study included 291,995 participants from the UK Biobank, comprising 77,187 with metabolic dysfunction-associated steatotic liver disease (MASLD), 22,190 with metabolic dysfunction and alcohol-associated liver disease (MetALD), 5474 with alcohol-associated liver disease (ALD), and 187,144 without SLD. Cox proportional hazards models were used to assess CVD risk associated with numbers of LDL-C, Lp(a), and hs-CRP controlled within the target range. During 12 years of median follow-up, 24,251 CVD events were documented, with 19,661 coronary heart disease and 5600 stroke. Among individuals with various SLD subtypes, those with all three factors controlled had the lowest risks of CVD, with HRs (95% CIs) of 0.65 (0.58, 0.72) in MASLD, 0.61 (0.49, 0.76) in MetALD, and 0.57 (0.35, 0.93) in ALD when comparing to zero-factor control. In addition, among individuals with SLD subtypes achieving all three factors within target ranges, the HRs (95% CIs) of CVD were 0.97 (0.88, 1.07) in MASLD, 0.90 (0.75, 1.08) in MetALD, and 0.63 (0.42, 0.95) in ALD, as compared with non-SLD controls. Similar association patterns were observed for coronary heart disease and stroke. Participants with various SLD subtypes who had optimally controlled LDL-C, Lp(a), and hs-CRP showed no excess or even lower risk of CVD as compared with the general population. Not available.

Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2-3-fold increase in neuropsychiatric co-morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ongoing pain to emotional disorders. This review systematically explores epigenetic signatures in supraspinal integration hubs, notably the limbic-paralimbic networks and prefrontal regulatory circuits. The identified epigenetic signatures encompass dysregulation of DNA methyltransferases (DNMTs), RNA modifications, histone post-translational modifications and locus-specific alterations, including aberrant methylation at the brain-derived neurotrophic factor (BDNF), opioid μ receptor and transient receptor potential ankyrin 1 (TRPA1) gene loci. Additionally, they involve dysfunction of the glucocorticoid receptor (GR)/corticotropin-releasing factor (CRF) axis via epigenetic modulation. Building on these findings, we evaluate therapeutic strategies addressing epigenetic dysregulation. While preclinical data demonstrate the efficacy of histone deacetylase (HDAC) and DNMT inhibitors, clinical translation faces significant barriers, including limited blood-brain barrier permeability. Notably, our analysis highlights the benefits of combining pharmacological interventions with non-invasive neuromodulation for enhanced co-morbidity management. Looking forward, this review proposes innovative approaches that leverage CRISPR-based chromatin editing platforms, biomimetic nanocarriers for neuron-specific delivery and closed-loop neuromodulation integrating real-time biomarker feedback, collectively establishing a precision medicine framework for pain or neuropsychiatric co-morbidities.

This study investigates the independent and interactive effects of apolipoprotein E (APOE) genotypes and white matter hyperintensities (WMH) on distinct neuropsychiatric symptom (NPS) phenotypes in patients with Alzheimer's disease (AD). We enrolled 325 AD patients consecutively diagnosed at a specialized memory clinic between May 2024 and May 2025. All participants underwent comprehensive clinical assessments-including the Chinese Mini-Mental State Examination (CMMSE), Activities of Daily Living (ADL) scale, and the Neuropsychiatric Inventory (NPI)-as well as 3T brain MRI for WMH quantification and APOE genotyping. First, we compared NPS profiles and cognitive/functional scores across APOE genotype groups (ϵ2/ϵ2-ϵ2/ϵ3, ϵ3/ϵ3, ϵ3/ϵ4, ϵ4/ϵ4) using analysis of variance (ANOVA) or Kruskal-Wallis tests, as appropriate. Second, we applied mediation analysis (PROCESS macro Model 4, 5,000 bootstrap samples) to examine whether WMH burden mediates the association between APOE genotype (X) and outcomes including CMMSE total score and domain-specific NPS subscores (delusions, agitation, irritability, euphoria). Significant differences emerged across APOE genotypes in both cognition (CMMSE, p < 0.05) and functional status (ADL, p < 0.05). At the symptom level, carriers of at least one ϵ4 allele exhibited higher agitation scores than non-carriers (p < 0.05); notably, the ϵ4/ϵ4 homozygotes showed significantly greater severity in delusions, agitation, irritability, and euphoria compared with all other genotype groups (all p < 0.05). Mediation analyses revealed no statistically significant indirect effect of APOE genotype on any outcome via WMH, indicating that WMH does not mediate these associations. Instead, APOE genotype exerted robust direct effects on both cognitive performance and specific NPS domains. APOE genotype-particularly the ϵ4/ϵ4 homozygous status-is associated with more pronounced cognitive decline and a distinct, severe NPS profile in AD, especially involving delusions, agitation, Euphoria, and irritability. These associations are independent of WMH burden, suggesting that APOE exerts direct neurobiological effects on neuropsychiatric manifestations. Thus, APOE genotyping holds dual clinical value: not only as a well-established biomarker for AD risk and diagnosis but also as a potential prognostic indicator for behavioral and psychological symptoms-offering actionable insights beyond conventional neuroimaging markers.

Hepatocellular carcinoma (HCC) is a major malignancy with rising global incidence and mortality. Clinical treatment is limited by molecular heterogeneity and drug resistance. In recent years, endocrine-disrupting chemicals (EDCs) have attracted attention as emerging risk factors, but systematic pathogenic evidence for their roles in HCC initiation and progression remains insufficient. First, we predicted potential targets of EDCs using SwissTargetPrediction, STITCH, and ChEMBL, and intersected them with differentially expressed genes and key module genes from WGCNA in the GEO database to screen candidate key genes. Second, based on these candidates, we constructed diagnostic models using 14 machine-learning algorithms and evaluated feature importance via the SHAP framework to identify key biomarkers and their functional contributions. Molecular docking and molecular dynamics simulations were used to validate interaction mechanisms between EDCs and key target proteins. We then built a multivariable Cox proportional hazards model in the TCGA-LIHC cohort and performed stratified survival analysis, somatic mutation profiling, and immune evasion characterization. Subsequently, we evaluated the tumor immune microenvironment using CIBERSORT and ssGSEA, and integrated single-cell transcriptomic data to resolve cell-subtype heterogeneity, target expression distributions, and cell-cell communication. Meanwhile, we integrated the GDSC drug-sensitivity database to evaluate associations between risk scores and drug response, and conducted pan-cancer analyses to examine cross-cancer applicability. We identified 18 genes jointly associated with EDCs and HCC, significantly enriched in AMPK, p53, and FoxO signaling pathways and cell cycle-related pathways. Among models built with 14 machine-learning algorithms, CatBoost showed the best discriminative performance and identified CCNB2 and AKR1C3 as core driver genes. Docking and dynamics simulations indicated strong binding affinities and stable binding conformations between EDCs and target proteins including CCNB1 (-8.9 kcal/mol), AKR1C3 (-8.4 kcal/mol), and FADS1 (-8.5 kcal/mol). A multivariable Cox risk model based on nine key genes served as an independent prognostic predictor for HCC (HR = 1.746, 95% CI: 1.477-2.064, P < 0.001). The nomogram achieved AUCs of 0.836, 0.810, and 0.788 at 1, 3, and 5 years, respectively, indicating good predictive performance. The high-risk group was significantly associated with high tumor mutational burden (TMB), TP53 mutations, and low immune evasion scores. Regarding the tumor immune microenvironment, CIBERSORT and ssGSEA analyses showed marked enrichment of Tregs and M0 macrophages, while most effector immune cells and functions were suppressed. Single-cell transcriptomics further showed enrichment of endothelial cells, fibroblasts, hepatocytes, and macrophages in HCC tissues, with notable reductions in T cells, B cells, NK cells, and neutrophils, indicating an immunosuppressive microenvironment with stromal remodeling. Cell-cell communication analysis indicated that the MIF-CD74 receptor axis is central in immune-cell interactions. Drug-sensitivity analysis suggested that the high-risk group was more sensitive to GDC0810, BPD-00008900, and Fulvestrant, indicating potential beneficiary populations. Pan-cancer analysis showed that the risk model also had diagnostic and prognostic value in LUAD, KIRP, KIRC, and KICH, suggesting cross-cancer generalizability. This study systematically reveals that EDCs promote HCC initiation and progression by perturbing cell cycle, metabolic, and immune homeostasis through multi-target, multi-pathway mechanisms. The nine-gene risk model demonstrates superior performance in HCC diagnosis and prognosis and shows potential clinical translational value in drug-sensitivity prediction and pan-cancer analyses. This work provides a new perspective at the intersection of environmental toxicology and precision oncology and informs individualized therapeutic strategies. Show less

The abuse of methamphetamine (METH) is associated with an increased risk of Parkinson's disease (PD), whereas microglial polarization and glucose metabolism disorders are closely related to the progression of PD. This study aimed to investigate the specific molecular mechanism underlying the promotion of PD progression by METH through the regulation of microglial polarization and glycolysis. METH-induced C57BL/6 mice and BV2 cells were used to construct PD-like neurotoxicity animal and cell models for experimental investigation. Behavioral tests, immunohistochemistry and Nissl staining were used to assess the behavioral ability and neuronal damage of the animals. The levels of related proteins, inflammatory cytokines and glycolysis were detected using immunofluorescence, ELISA, Western blotting, and CCK-8 assays. METH treatment significantly promoted behavioral disorders in PD mice, reduced the number of TH-positive neurons, and aggravated neuronal damage in the substantia nigra (SN). In addition, METH decreased the M2 marker proteins Arg-1 and CD206 and increased the M1 marker proteins iNOS and CD86; the proinflammatory cytokines TNF-α, IL-β, and IL-6; and glucose uptake, glucose consumption and lactic acid production, thus promoting M1 polarization and glycolytic activity in BV2 cells. In terms of the underlying molecular mechanism, METH treatment significantly increased the level of LPA. METH promotes LPA expression via upregulation of LIPH expression, and activates the PI3K/AKT pathway. Knockdown of LIPH or treatment with BrP-LPA reduces the ability of METH to promote M1 microglial polarization and glycolytic activity. Furthermore, the addition of the PI3K/AKT signaling pathway activator 740 YP weakened the inhibitory effect of BrP-LPA on the above process. METH may promote M1 polarization and glycolytic activity in microglia by activating LIPH/LPA/PI3K/AKT signaling, thus promoting the progression of PD. Show less

Tripartite motif-containing protein 21 (TRIM21), an E3 ubiquitin ligase of the TRIM superfamily, modulates critical cellular processes including ubiquitination, autophagy, and oxidative stress response. Accumulating evidence highlights its context-dependent regulatory roles in hepatocellular carcinoma (HCC)-the most prevalent primary liver malignancy with high mortality and limited therapeutic efficacy. This review systematically summarizes the core mechanisms by which TRIM21 orchestrates HCC progression: ① Autophagy regulation: TRIM21 modulates HCC autophagy via multiple axes, including CCR4-NOT complex (TNKS1BP1/CNOT4)-mediated substrate ubiquitination, ATG14-dependent autophagosome initiation, and RETREG1-driven reticulophagy, with context-dependent effects on tumor proliferation. ② Drug resistance: TRIM21 enhances oxaliplatin sensitivity by ubiquitinating and degrading G6PD (the rate-limiting enzyme of the pentose phosphate pathway), while its role in sorafenib resistance involves dual pathways-the MST1/YAP axis and the ApoE/cholesterol/PI3K-AKT cascade. ③ Metastasis suppression: TRIM21 restricts HCC invasion and metastasis by ubiquitinating key oncoproteins, preserving epithelial integrity and inhibiting mesenchymal transition. ④ Reactive oxygen species (ROS) balance: TRIM21 regulates oxidative stress in HCC via the SQSTM1/p62-Keap1-NRF2 axis, coordinating with HIF1α to modulate antioxidant responses and tumor cell survival. Additionally, we discuss the regulatory significance of TRIM21 in HCC associated with hepatitis B virus (HBV) infection (via HBx/DNA polymerase ubiquitination) and nonalcoholic steatohepatitis (NASH) (via suppressing lipogenic enzymes to reduce steatosis-driven carcinogenesis). This review provides a theoretical basis for TRIM21 as a potential diagnostic marker and therapeutic target for HCC. Show less

Growing evidence implicates accelerated biological aging in environmentally induced psychiatric disorders, yet its role in metal-associated depression remains unclear. Using NHANES data, we evaluated associations between heavy metal mixtures and depression. Bidirectional mediation analysis was used to assess reciprocal pathways linking heavy metals, biological aging, and depression. Simultaneously, candidate genes linking heavy metal exposure to depression and biological aging were identified by mining the Comparative Toxicogenomics Database, analyzing differentially expressed genes (DEGs) from the Gene Expression Omnibus, and integrating the resulting evidence within a toxicogenomic framework to explore potential molecular mechanisms. The prevalence of depression among participants was 8.66 %. Metal mixtures significantly increased depression risk. Notably, cadmium and antimony increased the risk of depression (OR: 1.52, 95 % CI: 1.19, 1.94 and OR: 1.54, 95 % CI: 1.22, 1.93). Both metals have low thresholds (0.227 μg/L and 0.053 μg/L, respectively). Additionally, lead, cobalt, and molybdenum showed positive associations in specific models. Although population-level exposure to heavy metals declined from 1999 to 2020, concentrations remained sufficient to elevate depression risk. Our correlation analysis also identified a strong correlation between PhenoAge and chronological age (r = 0.84, P < 0.001). Mechanistically, we found that accelerated PhenoAge partially mediated the associations of several metals with depression risk, including monomethylarsonic acid (β = 0.004; 95 %CI: 0.003,0.006), cadmium (β = 0.006; 95 %CI: 0.003, 0.010), lead (β = 0.009; 95 %CI: 0.006, 0.011), cobalt (β = 0.010; 95 %CI: 0.006, 0.013), molybdenum (β = 0.009; 95 %CI: 0.006, 0.011), and antimony (β = 0.008; 95 %CI: 0.005, 0.011). Pathway analysis and DEGs implicated the contribution of neurodegeneration-multiple diseases pathway, with core molecular targets centering on BDNF, IL6, GSK3B, PTGS2, and SOD1.

Fear of progression (FoP) is a prevalent psychological issue among stroke patients. Previous studies failing to distinguish characteristics of patient groups with varying FoP levels. Latent profile analysis (LPA) classifies individuals into distinct subgroups via continuous FoP indicators, boosting classification accuracy by accounting for variable uncertainty. Given FoP's heterogeneity, investigating FoP profiles and their influencing factors in stroke patients is clinically significant for personalized psychological care and improved patient quality of life. A total of 366 stroke patients were selected as study subjects through convenience sampling, and a cross-sectional survey was conducted. FoP was assessed using the Fear of Progression Questionnaire-Short Form (FoP-Q-SF, 2 dimensions, 12 items). Independent variables included demographic characteristics, clinical indicators, the Recurrence Risk Perception Scale for Stroke patients (RRPSS), and the Medical Coping Modes Questionnaire (MCMQ). LPA was performed on the FoP-Q-SF items to identify subgroups. The R3STEP method was used to analyze influencing factors of subgroup membership, and the BCH method was applied to compare differences in distal outcomes across subgroups. Statistical significance was set at The study sample had a mean age of 63.93 ± 10.58 years, with 70.5% males and 65.0% first-ever stroke patients. Two latent profiles were identified: Low-FoP Adaptive Type (C1, 48.6%) and High-FoP Sustained Type (C2, 51.4%). The R3STEP showed that age 18-59 years (OR = 0.476, 95%CI = 0.245-0.924, This study revealed significant heterogeneity in FoP among stroke patients. Age, hypertension comorbidity, excessive recurrence risk perception, MCMQ-confrontation, and MCMQ-avoidance were associated with high FoP. Healthcare providers should prioritize identifying high-risk individuals and develop tailored interventions to reduce FoP and improve rehabilitation outcomes. Show less

p-Synephrine (p-Syn), a natural alkaloid isolated from Citrus aurantium L., promotes fat oxidation and is therefore widely used as a weight loss dietary supplement. It was recently reported to exert a potent antidepressant effect. However, its molecular targets remain undefined. Gastrodin (Gas), extracted from Gastrodia elata Blume, exerts antidepressant effects by targeting Melatonin Receptor 1A (MT This study aimed to evaluate whether MT Network pharmacology was applied to predict potential targets and associated signaling pathways for p-Syn and Gas. Molecular Docking simulations were employed to predict the possible binding sites of MT Using a network pharmacology approach and in vitro assays, we found that both p-Syn and Gas bind to MT1, activate the ERK/CREB signaling pathway, and up-regulate BDNF. In vivo assays showed that p-Syn alleviated Reserpine (Res)-induced depression-like symptoms in AB zebrafish larvae and C57 mice. Furthermore, p-Syn and Gas showed a remarkable synergistic effect. This study identifies a novel target for p-Syn and provides new insights into the antidepressant mechanisms of p-Syn and Gas that may contribute to the clinical application of these compounds in the development of new drugs for the treatment of depression.

We recently showed that METRNL (Meteorin-like) protects against atherosclerosis. However, the mechanism for METRNL in atherosclerosis is largely unclear. This study aimed to demonstrate the relative importance of endothelial METRNL in atherosclerosis by comparing the effects of whole-body METRNL deficiency to endothelial-specific deficiency, and to show the subcellular distribution of endothelial METRNL and its role in mitochondrial homeostasis against atherosclerosis. Our study demonstrated that a deficiency in either endothelial or global METRNL exacerbated atherosclerosis to a similar degree in both spontaneous (age-related) and high fat diet-induced atherosclerosis, suggesting that endothelial METRNL is pivotal in the progression of atherosclerosis due to METRNL deficiency. Endothelial METRNL was diffusely distributed in the cytoplasm with subcellular localization to mitochondria, nucleus, endoplasmic reticulum, and Golgi apparatus (especially enriched in mitochondria and nucleus).

Given the potential of polyphenols to mitigate neurodegenerative diseases (NDDs), this meta-analysis investigated whether clinical evidence supports the use of polyphenols for neuroprotection and as nutritional strategies in NDDs. We analyzed different polyphenol types across seven NDDs, 13 studies involving 849 participants were included. Prespecified outcomes comprised global cognition (Mini-Mental State Examination, MMSE), domain-specific cognition (Alzheimer's Disease Cooperative Study-Cognitive Subscale, ADCS-Cog), activities of daily living (Alzheimer's Disease Cooperative Study-Activities of Daily Living, ADCS-ADL), neuropsychiatric symptoms (Neuropsychiatric Inventory, NPI), and selected biomarkers (plasma amyloid-β40 and brain-derived neurotrophic factor, BDNF). Reporting followed PRISMA 2020 guidelines, methods conformed to the Cochrane Handbook, and certainty of evidence was assessed using GRADE. Overall, polyphenol supplementation was associated with improved global cognition (pooled MD in MMSE = 2.06; 95% CI 0.62-3.49). In subgroup analyses, flavonoids were associated with a modest but significant improvement in MMSE scores, whereas stilbenes produced a significant benefit in daily functioning (ADCS-ADL) without clear gains in MMSE or ADCS-Cog and no consistent effects on NPI. Anthocyanidins, phenolic acids, and lignans did not significantly affect cognitive outcomes (MMSE or ADCS-Cog), and polyphenol subclasses did not yield robust or consistent changes in NPI or biomarker endpoints (Aβ40 and BDNF). Specific polyphenol subclasses therefore appear to confer selective cognitive and functional benefits, with stilbenes primarily supporting functional outcomes and flavonoids potentially enhancing global cognition.

Synaptic vesicle glycoprotein 2A (SV2A), a transmembrane protein widely localized to synaptic vesicles, serves as a key indicator of synaptic loss in Alzheimer's disease (AD). In this study, adeno-associated virus (AAV) was injected by brain stereotactic injection technique to construct SV2A-overexpressing APP/PS1 mice, then the effects of SV2A on amyloid precursor protein (APP) degradation and its molecular mechanism were further explored in vivo or in vitro. Our results demonstrated that SV2A overexpression significantly reduced Aβ plaque deposition in brain tissue of APP/PS1 mice. Mechanistically, SV2A was identified as a novel APP-binding protein that attenuated the amyloidogenic processing of APP by inhibiting its interaction with β-site APP cleaving enzyme 1 (BACE1). Furthermore, SV2A overexpression altered the subcellular distribution of APP, shifting its localization away from the endosomal-lysosomal compartments. Collectively, our findings unveil SV2A as a critical regulator of APP metabolism and propose it as a promising therapeutic target for intervening in the early pathological progression of AD.

Identifying high-performing advanced practice nursing roles and understanding the factors that contribute to their effectiveness are critical for advancing professional development, optimizing workforce deployment, and ensuring long-term sustainability in nursing. This study aimed to (1) identify distinct latent profiles of advanced practice nursing among specialist nurses in mainland China, (2) quantitatively examine the individual and contextual factors associated with high performance, as characterized by these profiles, and (3) qualitatively confirm the significant factors using explanatory semistructured interviews in the high-performance groups. A mixed-methods sequential explanatory design was used, in which quantitative data were collected first and subsequently explained through qualitative interviews. Certified specialist nurses from 16 hospitals across urban and rural areas of Shanghai were included. Latent profile analysis (LPA) was conducted using the five domains from the Advanced Practice Role Delineation tool as manifest indicators to classify nurses into distinct performance profiles. Multinomial logistic regression was used to examine potential determinants (e.g., job position) of group membership. Additionally, a backpropagation neural network (BPNN) was developed to rank the importance of contributing factors. Specialist nurses identified as high performers in the quantitative phase were purposively sampled for explanatory semistructured qualitative interviews. Three latent profiles emerged: high performance (26.1%), moderate performance (46.3%), and low performance (27.6%). Compared to APNs, staff nurses had significantly lower odds of belonging to the high-performance group ( Identifying the profiles of advanced practice nursing roles provides valuable insights for optimizing APN performance and informing targeted management and policy strategies. High-performing specialist nurses are positioned at the nexus of individual capability, interdisciplinary collaboration, and institutional support. Show less

Ischemic heart failure (IHF) is one of the leading causes of death in the world. Plasma apolipoprotein C3 (ApoC3) levels are significantly elevated in patients with heart failure and positively associated with the incidence of ischemic heart disease (IHD). However, the causal association between ApoC3 and IHD development is unclear. ApoC3 expression changes were assessed in plasma from IHF patients/healthy donors and cardiac tissue from rodent models. 10-week-old male human ApoC3 transgenic (ApoC3 Overexpression of human ApoC3 in ApoC3 ApoC3 overexpression could activate cardiac TLR2/NF-κB to trigger the inflammation, oxidation, and apoptosis pathways, finally aggravating IHF in mice. Inactivation of ApoC3 could significantly alleviate IHF in hamsters. Show less

Fusion genes are pivotal drivers of tumorigenesis, often generating oncogenic chimeric RNAs and fusion circular RNAs. However, the mechanisms by which these transcripts synergistically contribute to cancer progression remain poorly understood. Here, we identified a lung cancer-specific chimeric RNA KANSL1-ARL17A (chKANSARL) and its circular variant fusion circular RNA KANSL1-ARL17 A (F-circKA), both derived from the fusion gene KANSARL. Functional assays revealed that overexpression of either chKANSARL or F-circKA significantly enhanced lung cancer cell proliferation, migration, and invasion, while their knockdown suppressed these malignant phenotypes. In vivo experiments demonstrated that chKANSARL overexpression accelerated tumor growth in immunodeficient mice. Notably, coexpression experiments uncovered a synergistic regulatory interaction between F-circKA and chKANSARL, amplifying oncogenic effects. Mechanistically, miRNA sequencing and dual-luciferase assays revealed that F-circKA acts as a molecular sponge for miR-6860, thereby derepressing chKANSARL expression. Rescue experiments further validated this regulatory axis, wherein miR-6860 inhibition reversed the tumor-suppressive effects of F-circKA knockdown. Collectively, our study identifies and characterizes a novel F-circKA/miR-6860/chKANSARL regulatory axis, revealing how dual transcriptional outputs from the KANSARL fusion gene can synergistically drive lung cancer progression. These findings highlight a previously unrecognized layer of cooperative regulation between linear and circular fusion RNAs in oncogenesis and provide a new framework for understanding fusion gene-mediated tumorigenesis.
